An improved ink jet head for use with a drive circuit that includes a plurality of actuator units, each of the plurality of actuator units has a base plate defining a plurality of ink chambers on a first surface, a cover plate disposed on the base plate to cover the plurality of ink chambers, a plurality of drive electrodes formed on side surfaces of each of the ink chambers, a plurality of extended electrodes extending from the side surfaces which are formed on the second surface of the base plate, and a plurality of connecting electrodes, disposed on the cover plate, that connect the electrodes and the drive circuit. The extended electrodes formed on the top of the base plate on the first actuator are connected to the plurality of connecting electrodes disposed on the cover plate on the second actuator. The actuator units are capable of forming a multi-layered ink jet print head by stacking the plurality of actuator units one upon the other in a simple and efficient manner.
